Design and development of gasoline injector test bench

Abstract

Gasoline injectors are very important parts of gasoline injection system on internal combustion engines. Accurately identifying the parameters of a gasoline injector allows us to use it more efficiently, for example, building a custom electronic fuel injection. This research presents the results of the development of a gasoline injector test bench. The control circuit uses the Arduino Uno R3, the gasoline injection amount is determined by load cell, the gasoline pressure in the injector is changed by a pressure regulator. The research results show that a high resistance gasoline injector test bench has been successfully developed and a method of determining the parameters of the injector is built so that the gasoline injection amount can be calculated according to the injection time.
